将输入添加到lis时出错

Question

我试图创建一个程序，要求用户输入他/她的名字，并记录到一个列表中的输入（正在努力字典，但似乎我做了一个嘘嘘！）但它返回“TypeError:只能将list（而不是“str”）连接到list”。以下是代码。谢谢提前。你知道吗

namedic = []
while True:
    print ("Please, enter your name:")
    name = input()
    if len(name) > 3:
        print ("Welcome")
    else:
        print ("Ew, your name have less than 4 letters! Gross! Try a new one")
        continue
    namedic = namedic + name
print ("Ah, your name have at least 4 words, good name.")
for name in namedic:
    print (name)

Answer 1

正如错误所示，+操作符不用于将元素附加到列表中。您可以使用append方法：

namedic.append(name)

Answer 2

你的错误代码是namedic = namedic + name。您要做的是将列表（namedic）添加到字符串（name）。你应该改做namedic.append(name)。你知道吗

Answer 3

#your code should rather be like this;
namedic = []
while True:
    print ("Please, enter your name:")
    name = input()
    if len(name) > 3:
        print ("Welcome")
    else:
        print ("Ew, your name have less than 4 letters! Gross! Try a new one")
        continue
    namedic.append(name)
print ("Ah, your name have at least 4 words, good name.")
for name in namedic:
    print (name)
